Daisy,
When it rains it pours, doesn't it? Is there anyway you can get assistance with your husband's mother? Other siblings? Home health? The journey you are about to undergo will require more strength than you ever knew you had - you can do it, but you need to reduce ALL the burdens you can as this will take everything you have and then some. I know you probably feel you can handle it all, but as time goes on, please don't feel guilty if you have to let people step in and take on some of the other responsiblities. Please take care of yourself. You're husband will need both his strength and yours for a long time to come.
You don't say what part of Texas you are from. I am in the panhandle. If there is ANYTHING I can do, please let me know.
Tonya
